Help with calculus question in economics

Hi guys... Not sure if this is the right forum to post my question in but i'll give it a go anyways.
Here's the question:
Total Revenue is price times quantity. Suppose the demand curve for a good is
given by Q = A BP . Find the eect of a price change on revenue, i.e., take the
derivative of revenue with respect to price. When is it positive? When is it negative?
What role does elasticity play?
